Quantum reading of digital memory with non-Gaussian entangled light

It has been shown recently (Phys. Rev. Lett. 106, 090504 (2011)) that entangled light with Einstein-Podolsky-Rosen (EPR) correlations retrieves information from digital memory better than any classical light. In identifying this, a model of digital memory with each cell consisting of reflecting medium with two reflectivities (each memory cell encoding the binary numbers 0 or 1) is employed. The readout of binary memory essentially corresponds to discrimination of two Bosonic attenuator channels characterized by different reflectivities. The model requires an entire mathematical paraphernalia of continuous variable Gaussian setting for its analysis, when arbitrary values of reflectivities are considered. Here we restrict to a basic quantum read-out mechanism with non-Gaussian entangled states of light, with the binary channels to be discriminated being ideal memory characterized by reflectivity one i.e., an identity channel and thermal noise channel, where the signal light illuminating the memory location gets completely lost (zero reflectivity) and only a white thermal noise hitting the upper side of the memory reaches the decoder. We compare the quantum reading efficiency of entangled light with any classical source of light in this model. We show that entangled transmitters offer better reading performance than any classical transmitters of light in the regime of low signal intensity.Comment: 7 pages, 6 figures, To appear in Phys.

16TH CENTURY ENGLISH POETRY:CRITICAL EVALUATION.

It was the renaissance in the sixteenth century which gave birth to a variety of style and encouraged experimentation in English literature. For the first time the poets experimented with Italian style and created sonnets. The term modern was never used before, however with the change in the structure and form, the term “Modern English Poetry” was used to identify these newly developed poems. Courtly poets Wyatt and Surrey introduced new style, rhythm and form in English poetry which was identified as the modern English poetry since they were the first reformers in English metre and style and changed the traditional style. The essay here will study about the birth of modern English poetry and how it evolved during the age in the expert hands of Wyatt, Surrey, Spenser, Shakespeare, Sidney etc. It will further highlight the characteristic of the modern poetry of the period and highlight the fact that for the first time the greatest playwright Shakespeare wrote sonnets under the influence of Italian literature and others paved way for the heroic and epic poetry for the poets of the subsequent age. While lyrical style was predominant, but not the only form of the era, the poets experimented with early blank verse and also introduced the epic form and the dramatic or conversational poetry by William Shakespeare, Edmund Spenser, John Donne and Phillip Sydney which were highly appreciated and read even today

Effects of Circuit Resistance Training (CRT) for Cardiorespiratory health and fitness in persons with Paraplegia due to high thoracic spinal cord injury

The purpose of this study was to prove the safety and effectiveness of circuit resistance training in persons with high thoracic SCI. The total number of 15 subjects of age group 25-50 years diagnosed as paraplegia due to complete SCI were conveniently selected for this study. Circuit resistance training is the interventional program for this study. Metabolic and cardiac responses to exercise were continuously monitored via open-circuit spirometry and 12- lead Electro cardiography. The selected groups were given 12 weeks of circuit resistance training and examined for a period of 6 months. Before and after 12 weeks of CRT program, the pre and post training values of VO2max. and Hear rate were measured. The Paired t-test was used to compare the pre and post training values of VO2max. and Heart rate. Based on the statistical analysis the result of this study showed a significant increase in both VO2max. and Hear rate. Based on the data analysis and interpretation of VO2max. values the paired t-value of 7.89 was greater than the tabulated t-value of 2.14 at 0.05 level which showed a statistically significant difference between pre and post training values. Based on the data analysis and interpretation of Hear rate values the paired t-value of 18.69 was greater than the tabulated t-value of 2.04 at 0.05 level which showed a statistically significant difference between pre and post training values. CONCLUSION: The study showed that persons with paraplegia safely increased their endurance and muscular strength after 12 weeks of circuit resistance training. The study showed a significant increase in VO2max. and Heart rate while performing sioinertial resistance exercises after circuit resistance training program
